A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification, in which similar numerals of reference indicate corresponding parts throughout the several views.

The housing or casing of the machine is preferably rectangular as shown in the drawings, (see Fig. 3), and is formed of the spaced. outer and inner walls 1 and 2, pref erably formed of wood and metal respectively, sheet cork or other insulating material, as shown at 3 being located between said walls, an air space i being preferably provided between the walls.

\Vith this construction. the interior of the casing; is etliciently insulated against heat, preventing the surrounding atmospl'iere from materially raising the temperature within the casing.

A tank 5 preferably form-ed of sheet metal and rectangular in cross section, is suspend,- ed within the casing thus formed, the rear end thereof beinp closed and the forward open end extendiim tl'lIOllfIl] a suitable opening 6 provided in the forward end of the casing.

A piston 7 is slidably mounted within the tank 5 and is preferably provided with a felt ring 8 which may be lubricated with a fine oil, allowing the piston to move freely within the tank, the oil also slightly lubrieating the inner walls of the tank, thus eliminating any dii'liculty in forcing the semisolid contents from the tank.

Fluid under pressure, preferably compressed air, is admitted through the pipe 9, a coil 10 is located around the interior of the casing and communicates with the pipe 9, the other extremity of said coil extending into the rear end of the tank as at 11. It will be understood that in the event butter or the like is to be dispensed from the tank, the lower portion of the casing is filled with cold water, while if ice cream or similar substance is to be dispensed, the lower portion of the interior of the casing is filled with brine, ice and salt being packed over the brine in the upper portion of the casino", over the tank and around the coil 10.

The lid 12 of the casing is formed of the outer and inner walls 13 and 14, preferably formed of wood and metal respectively, a cork filling 15being provided therebetween.

When the interior of the casing is filled with brine and ice or cold water, and the lid place in position thereon, the interior of the casing is practically insulated against heat and the coil 10 being passed around the interior of said casing, the temperature of the compressed air is lowered before being admitted to the tank, thus preventing any melting" of the ice cream or butter by contact with the compressed air.

For the purpose of circulating the brine or cold water around the tank, the pipe 16 connected with a pump 17 the lower end of said pipe extending down into the brine or water. The pipe 18 is connected above the pump 17 and. communicates with the coils 19 which are located. around the tank 5, the opposite end of said coil forming an outlet into the interior of the casing as shown at 20.

It will be noted that t 1e warm brine or water which has passed through the coils if) is returned to the casing at a point considerably higher than the point where the brine or water is drawn into the coils, thus assuring that the coldest brine or water, which is necessarily located in the bottom of the casing, is drawn into the coils and the warm brine or water which is discharged from the coils is returned to the casing); at a higher point.

The pump which is provided for circulating: brine or cold water is preferably of the type shown in Fig. 15 and Fig. 16, and comprises the casing 17 which is elliptical in form and within which is mounted a pair of meshing. toothed wheels 21 mounted upon the shafts 22 which extend through one side of the casing: and. may be rotated in any usual and ordinary manner, the power means not being shown.

These wheels are arranged to be driven in the direction of the arrows shown in Fig.

V the water being drawn up through the inlet opening 2 3 and ejected through the outlet opening into the coils. It will be undm'stood that the water or brine is carried upwardly between the teeth upon the wheels, the wheels fitting snugly vithin the casing.

A cutting die is located in the open end oi the tank and arranged to cut the contents thereof into a plurality or": columns as it is forced T170111 the tank through said die. This die may be designed to term these columns of semisolid material of any desired cross sectional shape, but as it is des rable in dispensing butter ice. cream and he like to form the same in rectangular .ricks or prints the die illustrated in the erawings arranged to cut the semi-solid substance intoa plurality of rectangular columns.

This die is preferably provided with the spaced, vertical and horizontal blades 26, each of which is V-shaped in cross section, the sharpened edge 'ot each blade being located at the inner side of the die. The die is thus divided into a plurality of rectangular openings through each of which a column of butter, icecream or other sen1isolid substance may be forced.

The box separating frame 27 is slightly spaced from, and registers with the cutting die. being provided with the off-set cars 28 which register with the cars 29 upon the die tie bolts 30 which extend to the rear end of the tank being provided with the threaded extremities 31 which engage internal threads in the ears 28. thus clamping the die and separating frame tightly upon the open end of the tank.

This separating frame is provided with the spaced vertical and horizontal bars 32 registering with the cutting blades 26 upon the die. each or said bars being longitudinall'y grooved as at 33. thus forming the rec tangular flanges 34. which are o't proper size and shape to receive the open ends of the iliasteboard boxes or containers 35.

A guide space 36 is thus provided between the die and the separating frame, through which the vertically reciprocatingcut-off plate 87- is mounted. the grooved guide bars 38 extending upwardly from opposite sides oi? the frame, forming a continuation of this guide space arranged to receive the cut-off plate when the same is raised. one. of the guide bars 88 is slotted as shown at 39 to permit the lateral extension 4! upon the cutoil plate to extend therethrough.

The belt 11 is provided at spaced intervals, upon its upper surface. with the lugs 95 between which the rectangular frames 96 are arranged to be placed. each of these frames being open at its inner side and provided with the inwardly disposed flange or rib 97 around its outer side.

Each of these frames is arranged to snugly hold a plurality of pastcboard boxes or containers 35 in the position best shown in Fig. 9, the open ends of these boxes being disposed toward the mouth of the tank, the boxes equaling in number the rectangular flanges 32 upon the separating frame and being of suitable dimensions to receive said flanges when moved into engagement with the separating frame.

The frame 96 is provided with a longitudinally movable rear wall 90 provided with perforations as at 99 and arranged. to enrage the inturned flange. 97 when in the rearmost position. Spring fin ers 100 are provided upon the outer face of the movable, wall 98, these fingers being of the form best illustrated in Fin. 9, extending rearwardly and toward each other as at 101, the outer free extremities thereof being curved outwardly as at 102.

The cylinder 90 is provided with a piston having the elongated piston rod 103, upon the outer extremity of which is located the head 104: perforated. as at 105 and provided at its periphery with the annular flange 100 arranged to engage the spring fingers 1.00 upon the movable wall 98 when the piston is in its extended position.

A pawl 107 is pivoted at its forward. end as at 108 upon the piston rod 103, said pawl. having the forward, vertical face 109 and the rearwardly inclined face 110, a weighted tail portion 111 extending rearwardly and being arranged to normally rest upon the pin 112 extendingtransversely through the adjacent side of the piston rod.

This pawl is arranged to engage the lower end of the lever 113. pivoted intermediate its extremities to a stationary pc ion of the machine such as the laacket 11 1; mounted upon the cylinder 90, the upper er-ztremity of said lever being pivotally connected by means of the link 1153 to the arm 78 which connected intermediate its extremities to the valve 116, the opposite extremity of said arm being pivotally connected by the link 11'? to the arm 78 of the valve 118.

The valves 116 and 118 are both connected to the fluid supply pipe 119, a pipe 120 connecting the valve 116 to the forward or lower end of the cylinder .121, the valve 118 being connected to the rear or upper end of said cylinder by a similar pipe 122.

The cylinder 121 is provided with a piston, a piston rod 123 thereof being connected at its lower extremity to the cut-off plat-e which is arranged to be moved vertically in the guides above described by the movement of the piston within said cylinder.

A pawl. 124.- is pivoted at its forward end to the side of the piston rod 103 and provided with the forward. inclined face 125 and the rear vertical. face 126, the rearwardlv disposed weighted tail portion 12'? thereof normally restingupon the pin 128 which n-otrudes from the adjacent side of the piston rod.

The upper web of the conveyer belt 411 travels upon the horizontal platform which is provided with the central longitudinal slot 133 to accommodate the sprocket teeth 412 and with the longitudinal slot 134 to accommodate the depending; cam lugs 135. The cam lugs 135 are arranged to be received in the slots 17 of the pulleys 413 and 4A.

The operation of the device is as follows: the inclined head 64: being; in the dotted position shown in 5. the clutch 51 will be engaged with the block 419 and the brake shoe 5? will be released therefrom, the pulley 43 being thus driven through the shaft 44 and moving; the conveyor belt in the direction of the arrow shown in Fig. 1.

The frames 96 are filled with the empty pasteboard boxes or containers 35 and placed in succession upon the belt between the lugs 95. As each frame approaches a position opposite to the mouth of the tank the adjacent cam lug 135 will engage the arm 78, wiping said arm downwardly into the dotted position shown in 1, throwing the valve 86 t0 the exhaust position and opening the valve 85, admitting air to the rear end oi? the cylinder. 90 and starting to move the piston rod 103 toward the tank, the head 104k upon said piston rod moving from the dotted position to the full line position shown in Fig. 2.

Simultaneous with this n'ioveinent, the downward movement of the arm 78 to the dotted position shown in Fig. 1, will cause said arm to engage the arm 78', and move said arm from the dotted to the full line position shown in Fig. 1, throwing the valve 67 to the exhaust position and opening the valve 68, admitting air to the rear end of the cylinder 62 and moving the piston thereof outwardly, moving the inclined head 64L- from the dotted, to the full line position shown in Fig. 5. This movement of the inclined head (A will force the clutch member 51 out of engagement with the block 49 and throw the brake shoe 57 into engagement with said block, stopping the pulley 13 and the conveyer belt.

As the throw of the piston rod 63 is considerably less than the throw of the piston rod 103, tl e belt will have been stopped before the lunger head 104; engages the movable wall 98 ot the tlrame 96. As the head 10 1 reaches the limit of its outer movement, the boxes or containers 35 will be moved into the position shown in Fig. 9, forcing the open mouth of each her: around the adjacent rectangular flange 34'.

As this movement oi: the piston rod 108 takes place, the pawl 10? will engage the lever 113, moving said lever from the dotted to the full line position as shown in Fig. and through the link 11!) the valve 116 will he moved to the open position and the valve 118 to the exhaust position, admitting air to the lower end of the cylinder 121 and. raising the cut-oil plate till the lower end. thereof is moved, out of engagementwith the cutting die 25. as the ciiit-otl' plate moves upwardly, the pawl 1257 will ride over the lever 93 which is then in the dotted position shown in Fig. 1.

As the cut-oil plate is opened, the fluid pressure within the tank will move the piston 7 forwardly, discharging the contents oi the tank through the open end thereof, forcing the same through the cutting die and separating the butter or other semi-solid substance into a plurality of rectangular columns, corresponding substantially in size with the pasteboard containers, forcing one column into each container.

As the cut-off plate moves upwardly, the upper edge thereof will engage the arm 78 moving the same from the full line to the dotted line position shown in Fig. 2, re versing the positions otthe valves 116 and 118, moving the valve 116 to the exhaust position and the valve 118 to the open position forc ng the pi in within the cylin der 121 downwardly a moving the cutoff plate hack to the normal position, severing the columns of smi-solid substance which have been forced the tank.

lVith the dmvnward movement of the rut-oii plate, the pawl 137 will engage the lever 93 and move the same from the dotted hack to the full line position shown in Fig. 1, the link 92 raising the arm 78 and reversing the positions oi V tne valves 85 and moving the valve 85 to the exhaust position and opening the valve 85, admitting fluid to the forward or inner end of the cylinder 90,, forcing the piston thereof back-- ward.

A the piston rod 103 thus moved back to the initial, position, the head 1.0 1 thereof which is 'i'rictionally held in engagement with the movable wall 98, by means oi? the spring fingers 100. will move said wall into en ement with the ("hinge 97 and withdraw the frame 96 from the position shown in 2, allowing the belt, which before the forward movement of said piston, has been moved transversely upon the platform to the positioi'i shown in l 2, to move back against the flange 136.

As the frame 96 engages the flange 1.36, the further inward nmvement of the piston rod. 10?, will disengage the head 104i from the spring lingers 100. The pawl 1241- upon the piston rod 103 will engage the lever 129 and move the same from the full line to the dotted line position shown in Fig. 2 and through the link 1231 and bell crank S-lwill. raise the arm '78 from the full line to the dotted line position in Fig. 1, reversing the movement of the valves 67 and 68, moving the valve (38 to the exhaust position and the valve 67 to the open position, adn'iitting fluid to the forward end of the cylinder 62 and moving the piston therein baclnvardly. w itl'ulrawing the inclined head 6 t from engagement with the clutch 51, allowing the spring 55 to throw said clutch into operative position and allowing the spring (50 to release the brake shoe 57, per-- mitting the pulley 4-3 to rotate with the shaft 41: 1, starting the conveyor.

The irame 96 having been moved sutlieiently to clear the [illed containers from engagement with the separating frame, the frame 96 C(mtaining the tilled boxes, will he moved away from the mouth of the tank and is deposited upon the stationary table 138. This operation is continued as each frame 96 is moved into position adjacent to the mouth of the tank.

It will of course he understood that during the above described operation of the machine the various plug valves, which control the fluid cylinders, will remain in the positions oi? adjustment shown until moved by the various parts of the machine which are arranged to contact therewith.

It will be evident from the above and the accompanying drawings, that a machine is thus provided which requires only the placing of the frames 96 filled with empty containers or boxes upon the conveyor belt, the entire operation of stopping the belt as the frame reaches the mouth of the tank, moving the boxes into engagement with the separating frame, opening the cut-off plate, forcing the semi-solid substance through the cutting die, separating the same into a plurality of columns and forcing one column into each empty box, closing the cutoff plate which severs the contents of each box, moving the filled boxes and the frai'ne 96 out of engagen'ient with the separating frame and starting the conveyer belt to carry filled boxes away from the machine, being automatically accomplished without the necessity of any manual operation and eliminating entirely the human element.
